Internet giants Google and Microsoft have officially given their web-based energy management tools the Donald Trump (as in You’re Fired!), and lannounced that they would be closing them down. But there are still over a dozen options trying to tackle this difficult market.

In the wake of Google pulling the plug on its energy tool PowerMeter, Microsoft says it has now killed its energy service, Hohm, too. Microsoft writes on its blog that it will discontinue its Hohm service starting on May 31, 2012.

Consumer electronics bigwig Belkin has just launched a $30 device that can measure household power use by watts, dollars and carbon footprint from any appliance or device that plugs into a wall socket. But will consumers pay for DIY home energy management? That’s still unclear.

Will Google (s GOOG) one day monitor and manage the energy consumption of your washer and dryer? The company has partnered with chip maker Microchip (s MCHP) to work with developers in order to create embedded devices that are compatible with PowerMeter.
